controller'sespecially designed and adapted .among other uses to be employed on circuits carrying currents of high potential.

'The present invention has for its object to provide a switch or circuit controller, which is simple and efficient in operation and with which the danger ofshocks to the operator is eliminated or at least reduced to a minimum, as will be described.

These and other featuresof this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a perspective of a switch or circuit controller embodying this invention. Fig. 2, a similarview with the oil well or receptacle removed. Fig. 3, a view like F ig. 2,- but more in perspective with the switch in its open position. Fig. 4, a detail in plan 'to' be referred to. Fig. 5, an enlarged detail in vertical section and elevation to be referred to, the section being taken on the line 5*5," Fig. 7. Fig. 6, av detail of one of the locking bars for the oil well, and Fig.7, a partial transverse section and end elevation to be referred to.

In the present instance, the invention is shown as embodied in a three polo double break switch, having three movable membersa, b, c, which cooperate with three sets of pairs of stationary members as will be described. Each movable member may be made as herein shown and consists of a contact member 10 composed of a plurality of laminations or brushes. which are secured between the two parts 12, 13 of a holder, by

means of a screw 14 (see Fig. 5).

' The part 13 of the holder is providedwith tially the length of the laminations of the movable contact member 10 to firmly support the same, and is provided at its opposite endswith arms 18, to the opposite sides of which are secured yielding fingers 19 having contact pieces 20 secured to their upper ends, and formin auxiliary contacts, as will be described. l lacli' end of the laminated contact member 10 cooperates with a fixed contact member, preferably of the co'nstructure herein shown and consisting of a flat metal plate or block 21 Lawing extended from its upper surface clamping lugs 22, which are suitably grooved on their adjacent surfaces to form a socket for the reception of the lower end of a metal rod 23, with which the lugs are firmly engaged by the clamping screws 25, (see Fig. 7). This coin struction of the stationary contact member enables the latter to be quickly and easily upright 28. said plate having suitable holes or openings for the passage of the rods 23 above and below the same.

One of the features of this invention-con sists in a novel insulator for electrically separating the contact supporting rod 23 from the metal plate or frame 26, and for permitting the terminal which cooperates with the line cable or conductor 29 to be soldered thereto before said terminal is fastened to the rod 23. For this purpose the insulator is composed as herein shown of three members or sections 30. 31 and (Figs. 5 and 7), the section 30 being located below the frame or metal plate 26 and comprising a sleevehaving a depending flange 34 atits lower end and an enlarged socket 35 at its upper end, into which extends the portion of the sleeve 3 which projects through the hole in the frame 26. The section 81'is provided at its upper end above the frame 26 withan annular flange or lip 36, forming a socket 237 into which extends the reduced'lower end 38 of the section 32, which is provided with a shoulder 39 resting upon the flange 36 (see Figs. 5 and 7).

iolts 4&6, by turning extended through the upright portion 2 of the supporting; lranic lhrough an upright post or wall (56 to which lhc su 'iportiug frame is secured, and through a plate or :asting 67 secured to the front side of lhe post or wall The end of i'll.) llllli (i2 at the front side oi the post or wall 06 is pivolallv securedlo a lever (39 which is pirv oted at its lower end to a lug or projection (0 on the plate or casting; G7. The lever (3%) when turned into a sul'istnntially vertical position shown in Figs. l and 2 moves lhe link 62 in a substantially horizontal path and causes the inner end of the slot (-3 to engage the pin and more, the toggle lm ers 60 into their straightened position shown in Fig. This movement ol the toggle turns the lever 50 on its pivot so as to elevate its free end and thereby, through the linl: 52- and rod 58 lift the plate 0|: carrier 16 and the movable conta'ct memliicrs alilru-herl there to up into the position shown in Figs. 2 and 5, in which position th main n'lovable contact members or spring brushes 1 are engaged with the fiat underside of the stationary contact members or plates 2i, while the auxiliary movable contact members are engaged with opposite sides of the plates or stationary contact IXlQllll'HlS 2i, thu'sclosing the switch or circuit controllt-lr.

Provision is made or looking the switch in its closed position just described which may be accomplished by locking device, herein shown as a latch or hooked lever '74: pivoted between lugs T5 on the plate (37 and adapted to engage the operating lever (39, when the latter is moved into its closed position shown in Figs. 1 and Q, and provision is made for releasing said level; which may be accomplished by a sliding rod or plunger 1'6 movable in the handle 77 of the lever 69, said handle being made hollow to permit the rod. ill to extend through the same so as to be capable of engaging the free end of the latch T l and depress it against. the action ol :1 spring (not shown), which norn'mlly llfllds the latch up into engagement with ll e lever (39. The releasing rod Yb extent above the haudie and can be depressed to engage the lat h 7 1- by the thumb of tho operator, and said rod may be restored to its normal or projecting position shown in. l ig. 1 by a, spring located in the hollow handle and not herein shown. After the latch 74 has been (lepressed, the (lpfil'ililjl moves the lever back into the position shown in Fig. 3, which causes the link 62 to move the length.

of the slot 63 before it engages the center .pm 64 of the toggle and without movin motion and disen'g'agfi the .main contact t brushes 10 and then -e auxiliary contacts 20 from the stationarywontact members 21, and consequently effect a quick opening of the switch or circuit controller. The quick and accelerating downward movement of the movable contact members and their carricr is permitted by the loose or slotted connection between the link 62 andtlxe center pin 64 of the toggle, the slot 63 permitting the carrier 16 and movable contact memto move downwardly independently of the movement of the link 62 and the operating lever 69, and this movement may be hastened by iiicreasing the weight of the slab or carrier 16 to overcome the friction. When it is desired to close the switch, the operator moves the lever 69 from its substantially horizontal positionshown in Fig. 3, to the substantially vertical position shown in Figs. 1 and 2.

The switch above described is especially adapted for use in high tension 'circuits,-and provision is made for opening and closing the switch in oil or like non-conducting fluid. For this purpose, the supporting frame for the switch has detachably secured to it an oil well, comprising ame'tal box or vessel 80 open atit-s top for the reception of the parts of the switch located below the platform 26. said box being provided with a lining 81 of wood ,or other non-metallic material and with an inner box 82 of wood or other nonmetallic material, which inn'er box is also open at its top and is provided with vertical partition walls 83 arranged so as to separate the inner box into compartments correspondi-ngto .the number of the poles of the switch, said compartments being shown as three in number and marked 84, 85, 86- in Fig. 5, which are in communication with one another through vertical slots 87 inthe partition walls 83, in which slots movet-he carrier 16'common to the movable members of the switch.

Provision is made for securing the oil well to the supporting frame in a manner as will enable this to be done by a single operator from one end of the said frame, so that the danger ofshocks and the serious efl'ects'often resulting therefrom are avoided or at least reduced to a minimum, and so that the switches may be set close together side by side and thus economize in room.

For this bars 90 (see Figs..4,' 5, 6 and 7), which ex-' purpose I employ sliding bolts or I tend through suitable slots in the end walls of the metal boxv near the top thereof, and are provided with fingers 92, which pass above and rest ifp'onfingers or lugs depending from the supporting frame -26. The fin ers 92 and lu'gs'93 'areuso located with re ation 'to each other, that the bolts or barsf9'0 project through both end walls before are {said are engaged with said lugs, thus insuringthe oil well being firmly supported by the bolts when the fingers are engaged with the said lugs.

The locking bolts or bars may and preferably will be connected at one end by a cross or tie bar 94 having a depending lip 95 (see F ig. 5), which constitutes a handle, and the tie bar 94 has cooperating with it a removable pin 97, which is inserted down through a hole in a lug 98 on the end of the supporting frame 26,- and constitutes a lock for the sliding bolts or bars 90 and prevents accidental disengagement of the said bolts or bars from the lugs 93. The pin 97 may be attached to the chain 99 as represented in Fig.2. It will thus be seen, that the oil well may be quickly and easily detached from the frame, and again attached thereto, for it is only necessary for the operator to place one hand under the oil well to support the same, remove the pin 97 and withdraw the locking bolts 90 until they are disengaged from their supporting lugs 93, after which the hand supporting the well is lowereduntil its top clears the switch contact members; and to replace the same the reverse operations are performed. Additional lockin means for the sliding bars or bolts 90 may be provided, in the form of pins 100, (see Fig. ,4), which extend through suitable holes in the free end of the said bars and gage the end of the box if it should be attempted to entirely withdraw the said bolts or bars, and said pins also serve as stops for the bolts or bars-in their withdrawal movement, and are so arranged as to engage the box or well when the fingers are dischgaged from the lugs 93. The downward movement of the carrier 16 and its attached movable contact members may be cushioned by a washer 10]. of rubber or other yielding material (see Fig. 5), which rests on the frame 26 and is'engaged by the .fiange 57 on the rod 53.
